TO ALL WHOM iT M A.7 ClOITCERNa,`

'Be it known that we, GEORGE W. CHAMBERS and ISHAM WASHAM, of Talladega,in the county of Talladega, and State of Alabama, have-invented a newand useful Improvement in GultivatorandCotton-Plant Thinner and we dovhereby declare' that the following is a full,.,cleer, and exact.description thereof, which will enable others skilled in 4the -art tolnake'and nso the same, reference being hadlto the accompanyingdraw-ings, forming part of this specificatiomin ivhichl A 'V A Figure 1is a central vertical longitudinal section of our improved cultivatorand cotton-plant thinner.

' Thisinvention relates to asn improved machine for thinning andcultivating cotton plants, and consists in a four-wheeled-snzlkycrriage, to which are attached cultivators at vthe front and rear ends,and having bevel-gear connecting the front-.axle with a horizontallongitudinal shaft' upon which are placed any required number of hoes orchoppers for thinning thecotton plantsin the row at regulardistances-apart, by their rotation as the carriage moves through thefield, drawn by 'two ormore horses'. This machine accomplishes, in thework of thinnitig and hoeinglcotton plants, as much as, tenlieldhands-on'ordinary level land, and is a great laborsavingmachinq'ffespeeial valueto the country at-this period of disorganizedlah Jrrin `the southern States, and when every ecrt is 'being made toextend the cultivation of our great staple crop to supply the demand ofthe world for cotton. l i l w `We "ereawaretlat 'ciltivntorsand'chopperrcr-planbthinningmachineshane ,beenpreyionslmployed, but theimproved arrangements .ive have-introduced in the construction of ourmachine diiler fromV any known to us, and are essential to thesuccessful operation of such machines, as hereinafter particularlydescribed. I

Ail-represents a long rectangular carriageframe, mounted upon fourxvheels B B, and provided with the seat C for the driven', Atthe'front'endof the frame are placed `plonghs or cultivators a' a, onein each side of the middle, at such Vdistance apart as to straddle therow and throw,` oil" the earth en both sides of the plants. And

v at the Arear end of `the frame is .placed a V-shapedframe, D', enwhich'are fitted -a set of cultivators,'c e', so

ahranged as to'throw the soil back to theplants, and cultivate all theground to the middle het-Ween the rows. pon the a'xle E of the fronti'vheels is fixed a bevelwrheel, In, .gearing into the wheel b', on theend of a shaft, F, running lengthwise of the carriage. This shaftisprovided with any desired number of projecting hoes or choppers c c,placed upon itfat such distances apart, and related toeachother'.diametricallyin such a manner' that as the carriage is moved forward`the revolution of thev shaft F, corresponding with the advance made by'the rotationof the wheels through the action' of the-axle and thebevel-gear', shall strile the hoes or choppers in' regular successioninto the rows of cotton plants transversely, or nearly so, sndimakespaces 4between them for thimningl them properly, instead of Vtheordinary hand-chopping with a hoe. To the top of the hoe-blades may beattached a small bar i'or-palverizing the earth if necessary. The hoesmay be made adjustable to any requireddepth, .and the edges of theblades set at such angles'that the blade will not enter` the earthentiilely at once. The forward end of the shaft F has its hearing inasliding cross-piece,- G, iig. 3, operated by a handlever,Vd,placedconvenient'to the driver for dinsengaging the bevel-gear'temporarily if desired, when passing over uneven ground, ortransporting the machine. from place'to place. The machine can he soarrangedns to4 suit rows of any width, the wheels always running in thewater fnrrows.

` It will he seen fthat by employing four wheels on our machine, ittravels steadily', and ivill perform the work with nnch greater accuracythan a 'two-wheeled carriage, and by seating the driver on the carriagehis attention will be required only in driving the team properly, which's o great yadvantage in the 'operation over that ofl a mnchine'managcilWith-handles bya driver walking in the rear.

Having described our invention, we claim as new, and desire -to securebyLetters Patentl The arrangement of the lever d and the slidingcross-piece Gr, to engage and disengage the bevel-gear() Z1', in thcmanner and'forl the purpose'hcrein specified. A
